Bomb

TCG and CCG players use bomb to describe a very good, high-impact card. Left unanswered, a bomb can usually win a game on its own - because it is just that darn good.

For example, the card Pack Rat was a nearly unbeatable bomb in its Magic: The Gathering (MTG) draft and sealed formats. As such, players who opened a Pack Rat in draft or sealed would almost always play the card in their decks.

When is bomb used in TCGs and CCGs?

You are most likely to hear the word bomb used in regard to MTG and Hearthstone's limited formats, such as draft and sealed. This is because, in those formats, players are forced to play cards of lower quality - making bombs even more bomb-worthy. In constructed formats, players can fill their decks with good removal and bombs of their own, making bombs less OP than they are in limited.

A term used when you crack under the pressure and do very poorly on something; commonly utilized when you fail a test, interview, or audition; most often used as a verb, but can be used as noun.

A term that refers to a towering home run shot; comes from the similarity between bombs and home runs dropping from the sky and the destruction they can cause; commonly seen in the the phrase, "dropping bombs," which means "hitting home runs."
